“A while ago, Lear from Hong Kong, a Head-Fi sponsor, launched BD4.2 in both universal and custom shell. Tatco, the CEO of Lear, decided to organize an Australian tour for LUF-BD4.2 and a few listeners didn’t leave positive feedbacks as well as people who tried demos in some audio shops.
Honestly, I had some questions and doubts before getting it. BD4.2 comes in two versions. LCM (Lear...” --MikePortnoy

I've taken down my review of the Merlins and will repost it once I get them back. By now it's been 4 months and I've had them in my posession for no more than two weeks out of those 4 months.
Two weeks into the 3-5 week estimated turnaround time for my remolds/fixing and UM have gone back to maintaining radio silence. Not a word, not a single peep, no replies to emails....” --Sorensiim

“I purchased my Mentors in the first half of September 2014, and actually received them by the end of the same month. In all, it took only 2 weeks from the day my impressions were shipped to the day they arrived in my hands. I didn't pay for a rush order, so someone at UM must like me a lot. Thanks, anyway!
BUILD
The general build quality of the Mentor is decent. These are my...” --Malevolent

I love to see well-established audio companies with a solid lineup on offer. Someone like Parasound, Sennheiser, or PSB will almost always have their bases covered with budget, midrange, and fairly expensive models to choose from. That's great because it allows access for all sort of folks, regardless of budget. But you know what I love even more than...” --project86

“Big thanks to djvkool for generously lending me his personal unit for reviewing.
*I listen at relatively high volume, so my impressions will be based on this. Please be aware that there are differences in impressions at high volume and lower volume as noted by several members.

That's my full review. In summary: These are simply the best customs, and possibly the best headphones of any type, that I have ever heard. I prefer it to my JH13pro due to it's better deep bass response and more natural tone.
These sound great paired with a simple portable...” --project86

“This is the first review i am going to do on head fi . Firstly i am just a junior teenage audiophile so ya my review might be slightly inaccurate , just slightly. These Unique Melody mages have 4 balanced armature drivers in them, 2 lows 1 high and 1 mid. Now i will start of with build quality.
Build quality:
The build quality is superb i can say! When i compared it with my friend's jh 16...” --JuzModa

The company makes portable headphone amplifiers, some different types of cables and adapters and also custom-fit in-ear-monitors ("CIEMs"), but in the past, they've also made...” --ItsMeHere

If you are a fan of the Shure sound and have a broken pair of Shure SE530, or would like to try custom IEM but stay with a familiar sound signature and not spend 1000$ right away, the SE530x6 is the way to go. I am having a hard time finding anything wrong with them as I do not have better customs, but they challenge the best headphones I have (ATH ES10). These IEMs are quite easy to drive,...” --Mimouille
